So I've got a 2003 Mini Cooper S, and the buttons on the key fob just crumbled to bits. No worry, bought a new fob body, cut the key, then went to switch the guts over and realized one of the tiny micro-buttons fell off while it rattled around in my purse. So to fix my key, I'm looking for an itty bitty button that clicks onto that little black rectangle under the unlock switch. Looking at the lock button (they were the same) it seems to click on rather than need soldering? Any ideas on where I can get one or at least what it's called?
